NEEDS: Bears addressed one issue by placing non-exclusive franchise tag on Jeffery, all but ensuring he will remain in Chicago. $14.6 million tag leaves Bears with about $45 million in salary cap space to address holes. For all strides made in first season under coach John Fox and defensive coordinator Vic Fangio, lack of playmakers on defense was glaring weakness. Chicago tied for 22nd in sacks last season with 35 and for 30th both in forced fumbles (six) and interceptions (eight).

NEEDS: Detroit needs to work on replacing WR Calvin Johnson whether he retires or not. Lions also have to find help on offensive line because they've ranked among league leaders in sacks allowed for two straight years.

NEEDS: It never hurts to give QB Aaron Rodgers another target, especially after offense struggled in 2015. Packers could use consistent threat at tight end to open up middle of field. Or GM Ted Thompson could look for defensive help, perhaps inside linebacker with Clay Matthews appearing to be headed back outside. Defensive line could be replenished depending on if run-stuffing Raji returns. Offensive line depth might also be an objective, but Packers rarely splurge in free agency.

NEEDS: Vikings are unlikely to spend big this month, but offensive line depth is pressing matter, one that probably will require addressing through both in free agency and draft. Safety spot next to Harrison Smith remains an issue. If veterans Greenway and Newman aren't re-signed, they'll need replacements.
